Abstract
PURPOSE: To simplify and miniaturize the apparatus optical system, by separating and reconstructing various information recorded in multiple channels of recording medium in the hologram type in a single channel reconstruction optical system.
CONSTITUTION: When inputting into an optical transducer 13a from both first channel and second channel 3, 4, an amplifier 18 generates an output C in the presence of phase pulses A and B. Therefore, an analog switch 19 generates an output D in the presence of phase pulse A and an output E in the presence of phase pulse B. As a result, these outputs become integrated outputs F, G, causing individual outputs H, I to appear at output ends 24, 25 of the first and second channels, respectively. Thus, in a single channel reconstruction optical system, information in each channel may be separated and reconstructed.
